OIL-EMPTYING MECHANISM FOR MOTOBGASINGS.

Specification of Letters' Patent. Application `inea Junei, 1911.

Patented Oct. 24, 1911. Serial No. 630,722.

To all wwm 'it may concern:

Be it known that I, ISAAC KoEoHLIN, a citizen of Switzerland, residing at 7l Rue Danton, Levallois-Perret, Seine,in the Republic of France, have invented new and useful Improvements in Oil- Emptyiiig Mechanisms for Motor-Casings, of which the following is a specification.

This invention relates to improved oil emptying mechanism for motor casings havca-n be evacuated either entirely or partially, or down to a determined level in the casing as desired. Any excess of oil can consequently be rapidly removed from any of the compartments and with all possible cleanliness.

The annexed drawing illustrates by way of example the mechanism applied to a two compartment casing.

Figure l is a longitudinal section of the motor casing. Fig. 2 is a side view from the back. Fig. 3 is a plan view of the operating levler. ig. et isa section illustrating a detai At the bottom of the engine casing is a tube a in which another tube b actuated by means of the lever c or other appropriate device can slide, the lever c being arranged at a suitable spot for convenient operation by hand. The tube can have sliding movement but the lever c or a key or other suitable device prevents it from rotating. Each compartment of t-he casing carries centrally a partition p the height of which is equal t-o the height of the oil necessary. rlhe tube a of the casing is in communication with these compartments by two overflow .pipes d arranged on the separating partition and the height of which also determines the level of the oil and by four holes e in the bottom of the casing. The tube b has four holes f and can take three positions fixed by the notches -g L z' in any of which a ball j under the action of the spring lc can engage. The distances bet-Ween these holes f are the same as those between the holes e.

In the drawing the tube is shown aty the end of amplitude of movement to the right; the ball y' is in the notch g. In this position the holes f are not uncovered and the oil in the casing cannot be evacuated. When the tube Z) is pushed forward so that the notch la corresponds with the ball j, two of the holes f come opposite those made in the ing several compartments by which the oil tube d. f If at this moment the level of the oil in the casing is above the tops of the tubes d, the surplus flows through these holes, passes into the tube b and then into the chamber Z by the hole m. conducts this oil to the exterior, the stopper 0 ofthe same being unscrewed. -When the ball y' is engaged in the notch z' the four holes f of the tube b will be opposite four holes e contained in the casing is evacuated in'the same manner as previously described.

It is evident that the number of tubes and the number of outlet orices can vary with the number of cylinders .of the motor and the corresponding number of compartments ofthe casing.

Having now described my invention, what I claim asA new and desire to secure by Letters Patent is: y

1. An oil emptying mechanism for motor casings comprising in combination a tube a formed at the bottom'of the casing, a partition p formed in the middle of each compartment of the casing, an overflow pipe d formed in each partition, holes -e made respectively at each side of the partitions in the bottom of the casing and leading to the tube a, a sliding tube b arranged within the casing tube a, holes 7 made in the sliding tube b at the same distance one from each 'other as those madepin the bottom of the casing, means-for causing the interior of the sliding tube b to communicate with the exterior'and operatin ymeans adapted to bring the holes f of the s iding tube b successively opposite the overiiow pipes Zand opposite the holes e of the casing, substantially as described and for the purpose set forth.

2. An oil emptying mechanism for motor casings comprising in combination a tube a formed at the bottom of the casing, a partition p formed in the middle of each oompartment of the casing, an overflow pipe d in the bottom of the 'casing and all the oil` A conduit n formed in each partition, holes e made respectively at each side of the partitions in the bottom of the casing and leading to the tube a, a sliding tube b arranged within 'the casin tube a, holes f made in the sliding tube other as those made in the bottom of the c asing, a chamber Z'into which leads the sliding tube, a hole m formed in the sliding tube at its end leading to the chamber Z, a conduit at the same distance one from each n leading from the chamber Z to the exterior,

a lever c adapted to communicate tothe sliding tube b a lengthwise movement but preventing its rotation, and a locking device adapted to lock the sliding tube in the correct position for'retaining or emptying the oil, substantially as described and for the purpose set forth.

' 3. An oil emptying mechanism for motor casing's comprising in combination a tube a formed at the bottom of the casing, a partition p formed in the middle of each compartment of the casing, an overflow pipe d formed in each partition, holes e made respectively at each side of the partitions in the bottom of the casing and leading to the tube a, a sliding tube b arranged Within the casing tube a, holes f made in the sliding tube bV at the same distance one from each other as those made in the bottom of the casing, a chamber Z into which leads the sliding` tube, a hole m formed in the sliding tubo an' its end leading to the chamber l, a conduit n. leading from the chamber l to the exterior, a lever c adapted to communicate to the sliding tube ZJ a lengthwise movement but preventing its rotation, and a spring pressed ball adapted to be. engaged with notches g L z' formed in the sliding tube b to lock said tube in the correct position for retaining or emptying the oil, substantially as described and for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

ISAAC KOECHLIN.
